What is the Pythagorean Identity?

Group of answer choices

LaTeX: x^2+y^2=r^2 x 2 + y 2 = r 2 x 2 + y 2 = r 2 x 2 + y 2 = r 2

LaTeX: a^2+b^2=c^2 a 2 + b 2 = c 2 a 2 + b 2 = c 2 a 2 + b 2 = c 2

LaTeX: \sin^2\Theta+\cos^2\Theta=1 sin 2 ⁡ Θ + cos 2 ⁡ Θ = 1 sin 2 ⁡ Θ + cos 2 ⁡ Θ = 1 sin 2 ⁡ Θ + cos 2 ⁡ Θ = 1

LaTeX: x^2+y^2=1 x 2 + y 2 = 1 x 2 + y 2 = 1 x 2 + y 2 = 1

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer to this is a. a^2 + b^2 = c^2

step-by-step explanation:

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
